[ceph-users] Re: How to shutdown a ceph node
Yes I do. It's the ceph default and we use it on any cluster size (smallest is 3 Hosts with 6 disks each) and it removes a lot of headache. :-) And as OP did not provide and config I assumed that he uses the default.

Are you using size=3 replication and failure domain = host? If so you’ll be ok. We see folks sometimes using an EC profile that will result in PGs down, especially with such a small cluster. > On Dec 31, 2022, at 4:11 AM, Boris wrote: > > Hi, > I usually do 'ceph osd set noout' and 'ceph osd set norebalance' and then > shut down the OS normally. > > After everything is done I unset bot values and let the objects recover. > > Cheers and happy new year. > >> Am 31.12.2022 um 08:52 schrieb Bülent ŞENGÜLER : >> >> Hello, >> >> I have a ceph cluster with 4 nodes and İ have to shutdown one node of them >> due to electricity maintaince.

Hi, I usually do 'ceph osd set noout' and 'ceph osd set norebalance' and then shut down the OS normally. After everything is done I unset bot values and let the objects recover.
